MACHINE FOR PRINTING WOVEN FABRICS.

SPECIFICATION forming part of Letters Patent No. 440,750, dated November 18, 1890.

Application filed July 31, 1890. Serial No. 360,468. (No model.)

' other pile fabrics, cut or uncut; and it consists in combining with an engraved rolla suction-box, by means of which suction the air is drawn from the fibers of the fabric and coloring-matter drawn through to print or color the fabric at such places as the engraved print-roller shall place the coloringmatter. I attain these objects by the mechanism illustrated in the accompanying drawings, making a part of this specification, in which Figure 1 is a longitudinal and sectional elevation, showing in section parts of a machine for printing three colors and constructed according to my invention. Fig. 2 is a crossscction of a print-roller and suction-box, taken on the line X Y of Fig. 3. Fig. 3 is a longitudinal section of a print-roller and suctionboX, taken on the line X Y of Fig. 2.

Similar letters referto similarparts th ro u ghout the several views.

A represents the fabric; B, the engraved print-roll; D, the color-box, and a the cloctor. These rolls, boxes, and doctors are constructed in the usual mannerfor fabric-printing machines. The print-rollers, color-boxes, and doctors are arranged in a suitable frame and placed, one leading the other, on a horizontal line, as shown in the drawings.

P is a suction-box. This box should be made of brass and have a series of ribs V V. (See Figs. 2 and 3.) These ribs should be made of cold-rolled brass and smooth on the lower edge. The ends of the suction-box extend over the ends of the engraved printroll. These ends should be a good fit, but

not air-tight. From the top of each suctionbox is a pipe it having a stop'cock g.

F is an air-tight box. Gis an exhauster such as used for pumping air. cl (1 are carrying-rollers and should be spiked. The carrying-rollers on the printrollers are driven by spur-gears from the shafts of the print-rollers, and the roller to the extreme right drives by a chain belt the roller above it, and that roller drives the upper one on the left by a chain belt.

R is an endless Wire apron, the top part running on rollers S S. This Wire apron and carrying-rollers should be made of brass.

J is a metal box, in which is placed a series of steam-pipes p If these pipes are to be used for steaming the fabric, the pipes will be perforated with numerous small holes.

E E are drying-cylinders, which are constructed and operated in the usual manner to dry printed fabrics.

The operation of my improved printingmachine is as follows: The cloth to be printed moves in the direction indicated by the arrows, Fig. 1, as also do the engraved rollers, as indicated by the arrows on them. The engraved rollers B will raise coloring-matter in the engraved parts, and as the color in the engraved parts of the roller gets under the suction-box P the exhauster G will by the pipe h draw or suck the air from'the fabric under the boX PI The ribs V V prevent the fabric from rising from the roller B, and as the air is drawn from the fibers of the fabric the coloring-matter will take the place of the air and be absorbed by the capillary attraction of the fibers, the suction on the box P- being regulated by the stop-cock g in pipe h. The fabric passes from print-roller to print-roller and receives such number of colors as there are rollers and the design requires, and any number of colors may be used, as desired, or a design calls for. After printing, the cloth is carried by the wire-cloth apron R over the pipes 19 p and is steamed or dried, as the case may be. Some colors are made brilliant without steaming.

If pile fabrics are to be printed, I prefer to run the pile-face against the face of the printroller, and the color will be sucked through to the back, making a print as deep as the pile and Without crushing down the pile, and

\ thereby make an imperfect print.

It is obvious that my invention may be used to print on thin fabrics and the colors be suction-box provided with a series of ribs V V and a carrying-roller d, as shown, described, I 5

and for the purpose specified.

3. In a machine for printing Woven fabrics, the combination of a color-box, a doctor, an engraved roller, and a spiked carrying-roller d, as shown, described, and for the purpose 2o specified.
